If ever there was a Vatican rock star, it’s Pope Francis. The people’s pope has made significant headway in reforming the Catholic Church. Despite heading a Church with a long history of social conservatism, Francis has managed to shake things up in a number of ways: He’s declared that Catholic beliefs are consistent with evolution, he’s recognized climate change as a real threat, and he’s adopted a decidedly more liberal view of homosexuality.

But some people say he still hasn’t adequately addressed the dark cloud that’s hung over the Catholic Church for years, and many advocates are using his six-day, three-city tour of the United States as a chance to speak out.
